3 Claims. 1

This invention relates to insulator mountings for current carryingwires.

The main objects of this invention are:

First, to provide an insulator mounting for current carrying wires suchfor example as electrically charged fence wires which is effective forthe purpose and very simple and economical in structure and easilymounted on a post or support.

' Second, to provide a structure of this character in which theinsulator spools may be quickly and easily secured to a supportingspindle and removed therefrom repeatedly without injury to the parts.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A preferred embodiment of the invention is illustrated in theacompanying drawing, in which:

Fig. 1 is a fragmentary view partially in vertical section of aninsulator mounting embodying the invention mounted on an iron post orsupport, the initial position of the bendable spool retaining elementsbeing shown by dotted lines.

Fig. 2 is a fragmentary view in horizontal section of a modified form orembodiment of the invention in which the shank is adapted for mountingon a round post or rod.

Fig. 3 is a fragmentary view with the insulator spool omitted, showingthe supporting spindle welded to a supporting post.

In the accompanying drawing, i represents an angled fence post orsupport, and 2 a round post or support. The round post or supportillustrated is shown as solid but commonly such posts are tubular.

The insulator spool 3 is for-med of glass or porcelain or other suitableinsulating material and is provided with a longitudinal bore 4countersunk at 5 at its outer end. The exterior of the insulator spoolis provided with annular periph eral grooves 6 adapted to receiveattaching wires I for the current conducting Wires 8, a barbed wirebeing illustrated in the drawing although plain wires are quite commonlyused for electrically charged fence strands.

The spool supporting spindle 9 is provided with a shank Ill disposedangularly thereto. The

spindle and shank are formed of an integral rodlike member bent todispose the shank at an angle to the spindle. The inner end of theinsulator spool is countersunk at 5| to permit engagement of the spoolwith the shank H1 in spaced relation from the bend between the spindleand shank. In the embodiment of Fig. 1 the shank is provided with atapered tip H facilitating the driving of the shank into a wooden postand it is also threaded at I2 to receive nuts 13 for clamping the shankin a hole M of the post I. The end of the spindle has a longitudinalkerf l5 therein providing bendable fasteners it which may be spreadoutwardly into the countersink 5 as shown by full lines in Fig. 1 forretaining the insulator spool on the spindle with the spool resting uponor supported by the shank of the spindle. The bendable fastener elementspermit the removal of the spool 3 as occasion may require.

Electrically charged fence wires are frequently used to providetemporary enclosures although the electrically charged wires aresometimes used in strands of a wire fence. Where used to providetemporary enclosures it is particularly desirable to provide theinsulator mountings which permit the removal of the insulators.

In the embodiment shown in Fig. 2, the shank I1 corresponding to theshank Ill of Fig. 1 is provided with an eye l8 adapted to be sleevedover the support 2 and clamped in position thereon by means of the setscrew 19. In the embodiment shown in Fig. 3, the shank 2B is not pointedor provided with threads as in Fig. 1 but is designed to be welded asindicated at 2| to the post. It will be appreciated of course that theshank I0 could be welded instead of being driven into a post or securedby nuts. However, it is more economical to provide structures such asshown in Fig. 3 where it is intended to secure the shank by welding tothe post. The shanks may be welded to any type of fence post and theseare quite commonly of angle section.

While I have particularly stressed the use of the insulator mounting onelectrically charged fence wires there are many other uses, thestructure being particularly desirable where temporary current carryingwires are to be mounted for example in various kinds of fieldoperations, road construction, and the like.

I have illustrated practical embodiments of the invention which it isbelieved will enable those skilled in the art to adapt the invention asmay be desired for the particular conditions.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. An insulator mounting adapted for current carrying wires comprisingan insulator spool to which the wire may be attached, the spool having alongitudinal bore countersunk at its outer end, and a supporting spindleof generally circular cross section adapted to receive said insulatorspool and having its outer end slit longitudinally and diametrically toprovide bendable fastener elements spreadable into said countersink ofsaid insulator spool bore, the spindle having an integral laterallydisposed supporting shank with which the inner end of the insulatorspool is in supporting engagement when the spool is secured upon thespindle by said bendable elements thereof, the shank having a pointedend and also being threaded whereby it may be driven into a wooden postor support or secured to an iron post or support by means of nuts.

2. An insulator mounting adapted for current carrying wires comprisingan insulator spool to which the wire may be attached, theispool having alongitudinal bore countersunk at its outer end,.

and a supporting spindle adapted to receive said insulator spool andhaving its outer end slit 1ongitudinally to provide bendable fastenerelements spreadable into said countersink of said insulator spool bore,the spindle having an integral lateral- 1y disposed supporting shankwith which the inner end of the insulator spool is in supportingengagement when the spool is secured upon the spindle by said bendableelements thereof, said fastener elements being disposed in opposed,relation to each, other and being bendable towards and from each otherin a common plane, said countersink being of substantial dimensions andsaid fastener elements being bendable a substantial distance from eachother within said countersink.

3. An insulator mounting for wires adapted to be electrically charged,comprising an insulator having a longitudinal bore countersunk at itsouter end, and a supporting spindle having an.

integral shank disposed substantially at right angles thereto andadapted for attachment to a post, the spindle having a longitudinal kerfat its outer end providing bendable fastener elements, the spindle beingof such length that the insulator is supported by the shank when theinsulator is arranged on the spindle and its fastener elements bentoutwardly into the countersink thereof in retaining engagementtherewith, said fastener elements being disposed in opposed relation toeach other and being bendable towards and from each other in a commonplane, said countersink being of substantial dimensions and saidfastener elements being bendable a substantial distance from each otherwithin said countersink.
